Last week, we held the annual kickoff to the winter chloride volunteer water quality monitoring program. This event is an opportunity for the volunteers to visit socially, review the program, and see what kind of progress we've made. In the past, we've have presentations from the Missouri Department of Natural Resources and from the Metropolitan Sewer District (the entity responsible for stormwater quality in most of St. Louis city and county). This year, for the first time, the kickoff featured guest speakers from the scientific community. Two graduate students from the Hasenmueller Lab at Saint Louis University presented about their own water research.
Teresa Baraza Piazuelo shared her research on the movement of salt through roadside soils. Thus far in her project, she only had results on the sodium ions. She is finding that sodium is more concentrated near the road and that it seems to migrate down into the soil, though some is retained at the surface. She is eager to compare the movement of chloride, which is expected to move more readily than sodium through the soil.
Emily Deeba presented her work on the proportion of stormflow that is comprised of groundwater. She used concentrations of chloride that are found in groundwater and concentrations found in rainwater to perform a groundwater separation and identify what percent of the water in the stream during summer storm events is direct runoff versus older groundwater being pushed out of the porous limestone.
We closed the evening with a conversation about next steps for our program. While becoming more involved in the community of citizen science leaders, I have been reminded that the volunteers in citizen science programs are generally capable of accomplishing far more than just the monitoring aspect of projects like ours. Science is much more than data collection; based on our conversation last night, I can see that this group of scientists is ready to take another step. I hope you'll come back soon to learn more about our progress!
